Solr基本命令

啟動Solr

安裝Solr後，進入到Solr主目錄中的bin檔夾，並使用以下命令啟動Solr。

[Hadoop@localhost ~]$ cd
[Hadoop@localhost ~]$ cd Solr/
[Hadoop@localhost Solr]$ cd bin/
[Hadoop@localhost bin]$ ./Solr start

在 Windows 系統中使用以下命令 -

此命令在後臺啟動Solr，通過顯示以下消息監聽端口8983。

Waiting up to 30 seconds to see Solr running on port 8983 [\]
Started Solr server on port 8983 (pid = 6035). Happy searching!

在前臺啟動Solr

如果使用start命令啟動Solr，那麼Solr將在後臺啟動。然而可以使用-f選項在前臺啟動Solr。

[Hadoop@localhost bin]$ ./Solr start –f

在另一個端口上啟動Solr

使用start命令的-p選項指定一個啟動端口，可以在另一個端口啟動Solr，如下面的代碼塊所示。

[Hadoop@localhost bin]$ ./Solr start -p 8081

Waiting up to 30 seconds to see Solr running on port 8081 [-]
Started Solr server on port 8081 (pid = 10137). Happy searching!

停止Solr

可以使用stop命令停止Solr，如下示例 -

$ ./Solr stop

此命令停止Solr，顯示消息如下所示。

Sending stop command to Solr running on port 8983 ... waiting 5 seconds to
allow Jetty process 6035 to stop gracefully.

重新啟動Solr

Solr的 restart 命令會停止Solr 5秒鐘，然後再次啟動。可以使用以下命令重新啟動Solr -

./Solr restart

此命令重新啟動Solr，顯示以下消息 -

Sending stop command to Solr running on port 8983 ... waiting 5 seconds to
allow Jetty process 6671 to stop gracefully.
Waiting up to 30 seconds to see Solr running on port 8983 [|]  [/]
Started Solr server on port 8983 (pid = 6906). Happy searching!

Solr ─ help 命令

Solr的help命令可用於查看Solr提示及其選項的用法。

[Hadoop@localhost bin]$ ./Solr -help

Usage: Solr COMMAND OPTIONS
   where COMMAND is one of: start, stop, restart, status, healthcheck,
create, create_core, create_collection, delete, version, zk
Standalone server example (start Solr running in the background on port 8984):
   ./Solr start -p 8984
SolrCloud example (start Solr running in SolrCloud mode using localhost:2181
to connect to Zookeeper, with 1g max heap size and remote Java debug options enabled):
   ./Solr start -c -m 1g -z localhost:2181 -a "-Xdebug -
   Xrunjdwp:transport = dt_socket,server = y,suspend = n,address = 1044"
Pass -help after any COMMAND to see command-specific usage information,
such as: ./Solr start -help or ./Solr stop -help

Solr ─ status命令

Solr的 status 命令可用於在電腦上搜索和找出運行的Solr實例。它可以提供有關Solr實例的資訊，例如它的版本，記憶體使用情況等。

可以使用status命令檢查Solr實例的狀態，如下所示：

[Hadoop@localhost bin]$ ./Solr status

執行時，顯示上述Solr的status命令結果如下 -

Found 1 Solr nodes:

Solr process 6906 running on port 8983 {
   "Solr_home":"/home/Hadoop/Solr/server/Solr",
   "version":"6.2.0 764d0f19151dbff6f5fcd9fc4b2682cf934590c5 -

   "uptime":"0 days, 0 hours, 5 minutes, 14 seconds",
   "memory":"30.6 MB (%6.2) of 490.7 MB"
}

Solr Admin

啟動Apache Solr後，就可以使用以下URL訪問Solr Web介面的主頁。

• http://Localhost:8983/solr/
